Fresh clean install of latest core under MAMP. Bartik theme.
Using latest dev versions of Calendar, Date, Views and Ctools

Modules installed:
Calendar, Date, Views, CTools, (and Admin menu and Module Filter)
Steps to reproduce problem:
1. Create new content type Event
2. Add a Field of type Date to the Event content type. Accept all defaults
3. Add view from template "A calendar view of the 'field_date' field in the 'node' base table"
4. View displays. Click SAVE

WSOD appears, but view appears to have been created ok.

System logs shows one warning:

Same problem

I am getting the same message in my dblog, but here is some more info:

I do have Calendar module installed, but the field that the error is displaying on is a simple Date text field which has been newly created in a custom content form. It is not connected to a View or a Calendar (yet).

Upon saving the new form field, the error appears in the log. I think that may narrow it down to the Date module?

(Using Calendar 7.x-3.4, cTools 7.x-1.3+4-dev, Views 7.x-3.7, and Date 7.x-2.6 on Core v7.23 and custom Omega Theme)
